Mars in Taurus

Explanation: You can spot Mars in the evening sky tonight. Now home to the Perseverance rover, the Red Planet is presently wandering through the constellation Taurus, close on the sky to the Seven Sisters or Pleiades star cluster. In fact this deep, widefield view of the region captures Mars near its closest conjunction to the Pleiades on March 3. Below center, Mars is the bright yellowish celestial beacon only about 3 degrees from the pretty blue star cluster. Competing with Mars in color and brightness, Aldebaran is the alpha star of Taurus. The red giant star is toward the lower left edge of the frame, a foreground star along the line-of-sight to the more distant Hyades star cluster. Otherwise too faint for your eye to see, the dark, dusty nebulae lie along the edge of the massive Perseus molecular cloud, with the striking reddish glow of NGC 1499, the California Nebula, at the upper right.

说明: 今晚可看到火星。现为毅力号家园的火星，目前运行到天空的金牛座方向，与昴宿星团相去不远。就如这幅此区域的大视野深空影像所示，在3月3日拍照时，火星与昴宿星团发生大近合。位在影像中下方的明亮泛黄火星，与这个美丽的泛蓝星团相距只有3度左右。附近在色泽和亮度差可和火星争辉的，则是金牛座的最亮星毕宿五。位在影像左下缘的这颗红巨星，其实是在较远的毕宿星团的前方，二者只是恰好在同一视线方向。视野里这些太暗而肉眼不得见的黝黑尘埃云，位在大质量英仙分子云的边缘，而右上角的鲜明泛红天体，是编录号为NGC 1499的加州星云。
